Abstract (en)
[origin: WO2022137267A1] Described is a door (100) for aircraft, configured to be moved from a closed position of an outer shell of a nacelle to an open position to allow an inspection of an internal compartment of the nacelle, comprising: a first multilayer portion (40), comprising an inner layer (10), an outer layer (30) and an intermediate layer (20), wherein the intermediate layer (20) is made of composite material having an inorganic-based matrix and a carbon-based filler, the first portion being shaped in such a way as to have at least one substantially oblong stiffening protuberance (14, 14'); - a second layered portion (50) having an aerodynamic profile and shaped to be coupled to the first multilayer portion (40), the overall configuration of the door (100) being such that in an assembled configuration, and in a coupling between the first portion (40) and the second portion (50), the substantially oblong stiffening protuberance (14, 14') faces the internal compartment of the nacelle.
